Title: Improvements relating to rainwater down pipes and the manufacture thereof
IPC: E04D13/08
Filed: 1946-05-29
Abstract: 617,430. Tube expanders; aluminium articles. BIRMINGHAM ALUMINIUM CASTINGS (1903) CO., Ltd., and BERRY, J. D. May 29, 1946, No. 16400. [Classes 83 (ii) and 83 (iv)] [Also in Group XXVIII] A rainwater down-pipe comprises a pipe and a separately formed connection socket having a double taper bore at one end into which an end of the pipe is inserted and expanded so as to provide a positive interlock between the pipe and the double taper surface of the socket. A double taper surface 14, 15 is formed on the thickened wall 13 of a socket 10 preferably die cast in aluminium to which a pipe 11, preferably of aluminium, is to be secured. A sectional mandrel, with an external shape 28, 29 corresponding to the surfaces 14, 15 of the socket 10, is employed for the expanding operation and comprises a tubular member 18 divided into three or more segmental sections by radial slots 20, with three internal longitudinally cut grooves 21 and preferably three annular grooves 22, 23 and 24 holding garter springs 25 tending to close the segments of the mandrel towards the centre. A draw-bar 31 extends through the mandrel and is provided with a number of taper keys 32 in longitudinal keyways, the outer edge of each key bearing against a corresponding inclined base of a groove 21 in the respective section of the mandrel. The mandrel is mounted on a headstock 35 through which the draw-bar 31 extends to a yoke 38 to which piston-rods 39 of a pair of double-ended hydraulic cylinders 40 are secured. Movement of the pistons to the right forces the draw-bar 31 in the same direction and the taper keys 32 thereon further within the interior of the mandrel, forcibly expanding the mandrel sections and expanding the pipe 11 in the desired direction. Return of the pistons withdraws the taper keys 32 and permits the sections of the mandrel to withdraw under the action of the springs 25, enabling the pipe and socket to be removed from the mandrel. The pipes and sockets or other parts may be of other than circular section and the sockets may be formed with convexly curved surfaces. The double taper surface may have its longitudinal axis at an angle to the axis of the socket to allow for slight deviations from the straight in successive lengths of pipe. In a modification, a smaller type of apparatus is hand operated through screw gearing.

Abstract: 664,591. Impedance networks. PHILIPS LAMPS, Ltd. May 31, 1946 [Sept. 8, 1939], No. 16538/46. Class 40 (iii). [Also in Group XL (c)] A low-pass or band-pass filter of T or TT section terminated in a resistance R (the image impedance at zero frequency), is made to have substantially uniform input impedance by the shunt connection of an impedance 2Z 2 /n and of a negative resistance - R1 in the case of a TT section, 2Z 2  being the impedance of each shunt arm, or by the series connection of an impedance ¢ nZ and of a negative resistance - R1 in the case of a T section, ¢ Z1 being the impedance of each series arm, the equation n<SP>2</SP> = 1 - R/R1 being observed. The negative resistance may be constituted by the internal resistance of a screened grid valve but preferably a secondary emission valve is used as shown in Fig. 4. The filter section may be of the constant-k or m-derived type and any tendency for the amplification to fall off towards the limits of the working range may be reduced by inserting a half-section of m-type before the termination.

[Also in Division C6] A process for making a frozen concentrated milk-acidulating culture comprises propagating a starter culture in a non-milk medium, separating substantially all the cell-free medium, adding a diluent to the cells and freezing the cells and diluent. The concentrated milk-acidulating culture should contain at least 60 billion (6 Î 10<SP>10</SP>) cells per ml. of diluent. The diluent may consist of 90-70 parts by weight of normal saline and 10-30 parts by weight of glycerol. In the acidulation of cheddar cheese, cottage cheese or buttermilk, the concentrated milk-acidulating culture is dropped into the milk while still frozen. The non-milk medium, which is maintained at a pH in the range of 5.0-7.0 by the addition of specified alkaline materials, may comprise hydrolysed casein, lactalbumen or soya protein, peptones and tryptones, yeast extract, glucose or lactose, specified trace elements and soluble phosphates, and a silicone anti-foam compound, all in specified propositions. According to an Example, a commercially available Cheddar cheese starter culture is propagated initially in skim milk medium in two stages, and then in a non-milk medium (as given above). When the carbohydrate has been substantially completely consumed, the broth is chilled to 5‹C. and then is centrifuged whereby the cells are concentrated 20-fold. The cell concentrate is diluted with an equal volume of normal saline-glycerol solution and the diluted cell suspension is quick frozen in dry ice. The preparation of a Cheddar cheese employing the frozen concentrated milk-acidulating culture, is described in detail.

Artificial lines.-In telephone &c. net-works of the general types shown In Figs. 1 and 5, having impedance elements Z1, Z2, the characteristic impedance of the network is made equal to a constant resistance R for all frequencies by the use of series and shunt impedances Z11, Z21 connected by the relation Z11, Z21 = R<2>, as shown for example in Fig. 7. The network may be terminated at any mid-series point, such as 25<1>, 26', by a resistance R without affecting this characteristic impedance. The propagation constant of such networks is found to be a function of Z11/R, and a graphical method of obtaining the attenuation and phase components for the network of Fig. 7 is given. Fig. 15 shows the application of the invention to insert in a reactanceless circuit an instrument T with impedance without the introduction of reactance by using it as an element in a network section, an equivalent impedance Z11 and resistance R' being found by trial, and the impedance Z21 being calculated from the terminal resistance R. A network section may be inserted as an attenuation equalizer in a line whose attenuation curve is known, a suitable impedance Z11 being found by trial from the curve and the calculated equation for the propagation constant.

Waste gases from a drying oven are fed by a fan 6 through heat exchangers 7, 8 to a combustion chamber 9 within the same casing 15. A third heat exchanger 10 within the chamber 9 is of V- shape, and the gases are ignited in its inner space 17 by a pilot burner 18. A main burner 19 surrounded by an air supply tube 20 directs flames towards a main combustion chamber 12, open at both ends to allow recirculation of the burnt gas. Baffles 16, Fig. 4, connected to perforated walls 22 close the wide end of the space 17, and the partially burnt gases pass through the holes in the walls 22, entrained by the flames from burner 19. Burnt gases pass through at least the heat exchanger 10 to an outlet, to escape from a chimney, or return, with a desired amount of fresh air, to the drying oven. The casing 15 comprises an inner reflective metallic foil 31, spaced layers 30 of insulating material such as stone wool and an outer metal shell 32, Fig. 5.
